2 Claims.

This invention relates to a window structure for the cabs oflocomotives, particularly of the type used for switching, and has forits principal object to provide a window sash adapted to be used in themanner of the conventional sliding sash and also to be projected fromthe side of the cab and act in cooperation with the customary front andrear side wings during inclement weather to protect the engineer whenobserving signals in either forward or rearward directions.

Other objects of the invention are to provide a window sash structurethat is of simple and inexpensive construction and which may be easilyinstalled in the cabs of existing locomotives.

In accomplishing these and other objects of the invention as hereinafterpointed out, I have provided improved structure the preferred form ofwhich is illustrated in the accompanying drawings wherein:

Fig. 1 is a perspective view of the cab portion of a locomotive equippedwith a window sash embodying the features of the present invention andshowing the sash in projected position to cooperate with theconventional side wings in protecting the engineer when observingsignals in either a forward or rearward direction.

Fig. 2 is a section through the side portion of the cab showing thewindow sash in a customary position for closing the window opening ofthe cab.

Fig. 3 is a similar section showing the sash being projected to form anextended enclosure as shown in Fig. 1.

Fig. 4 is a similar section showing the sash in fully projectedposition.

Fig. 5 is a view from the interior of the cab showing one of the sashmembers in projected position and the other in retracted position.

Fig. 6 is a horizontal section on the line 6 6 of Fig. 2 with the sashclosing the window opening in the usual manner.

Fig. 7 is a similar section on the line 'I-'I with the sash in projectedposition.

Referring more in detail to the drawings:

I designates the cab portion of a locomotive of the diesel or electricaltype such as used for switching purposes. 'I'he cab of such locomotiveshave side window openings that are normally covered by a pair of sashwhich in times of good weather are carried within the cabI at the sidesof the window opening and are adapted to be slid over the window openingto protect the engineer in times of inclement weather. However, when itis necessary for the engineer to observe signals in either a forward ora rearward direction, the sash must be opened and the only pro-kltection is that afforded by the customary side wings which in thedrawing are designated 2 and 3. The side wings 2 and 3 only protect theeyes and face of the engineer from flying objects and wind currents inthe direction that the loco--` motive is moving. Consequently, the coldenters the cab through the open window and it is difficult. to maintaincomfortable conditions within the cab.

In carrying out the present invention, I have provided a pair of innersash units 4 and 5 that are adapted to be normally supported and movedacross the window opening in the manner of con-,

ventional sash and which are adapted to be projected in cooperation withthe side wings to protect the engineer and prevent entrance of cold airand the elements during inclement weather conditions. The side wingscomprise frames 6 having vertical styles 1 and 8 connected at their,

lower ends by a cross rail 9 and at their upper ends by an inclined railI0 that slopes downwardly from the side wall of the cab. Each frame car-I ries ak transparent panel II in the manner of an ordinary sash. Whilethe frames may be formed` of any material the vertical rail 'I and topand bottom rails I0 and 9. are provided with in-turne'dl iianges I2, I3,and I4 so as to cooperate with` the sash 4 and 5 in formingsubstantially weather tight joints as later described. The wings 2 and 3are pivotally mounted at the upper and lower ends on brackets I5 and I6that are carried by the side of the cab as best shown in Fig. 1.

The lower bracket includes a plate portion I'I- having notches I8 and I9which are adapted to be selectively engaged by a spring pressed pawl orslide bolt 20 to retain the wings against the cab or extended outwardlyat right angles thereto.

The bolts 20 are slidable in a depending portion' 2l of the bottom railsof the wings to engage the.

outermost notches I8 in holding the wings in exeyes 22 which may bereached by the-engineer through the window of the cab.

The sash units 4 and 5 are of a combined widthA to close the opening inthe side wall of the cab and to lap and seat upon the inner side of thewing anges I2, I3, and I4. Therefore, the combined width of the sashunits is slightly greaten than the width of the window opening so as vtoprovide a complete closure when the window sash are in the positionshown in Fig. 6 or in the projected position as shown in Fig. 7. Eachsash unit 4 and 5 is composed of a relatively small upper rectangularsection 23 conforming to the length of the upper inclined rails of theside wings and a. lower and larger section 24 which is of a length sothat when the sections are in the position shown in Fig. 2, the combinedheight of the sections will extend from the top to the bottom of thewindow opening. The sections 23 and 24 comprise frames 25 and 26 of anysuitable material, the upper frames 25 having top and bottom rails 21and 28 inter-connected by side rails 29 and 30 to contain a transparentpanel 3 l. The lower frames 26 have upper rails 32 and lower rails 33that are connected by vertical vside rails 34 and 35 to contain atransparent :panel 36. The rails 28 and 32 of the respective frames areconnected together by a hinge 31 so that the sections areinter-connected and may be moved as a single unit from storage positionto a position over the window opening as shown in Fig. 2, or to aprojected position as shown in Fig. 4.

The window sash thus described are mounted at their upper ends on aslide rail or track 33 that extends lalong the upper edge of the windowopening and is suitably supported at the ends by the end walls of thecab and at the center by a bracket 39, the rail being of suncient lengthto carry the windows when in retracted position at the sides of theopening as shown at the right in Fig. 5. lThe sash are slidablysuspended from the rail 38 by hangers 40 and 4I that loop over the sliderail and are attached to the upper rail of the sections 23 of therespective sash. Extending along the lower edge of the window openingand above a sill plate 42 is a similar slide or track 43 for slidablymounting the lower ends of the sash. The rail 43 is mounted in similarmanner and the intermediate portion is carried by a bracket 44 attachedto the sill rail 42.

In order that the lower sash may be projected and that the space be lledin at the -sill portionof the window, each sash includes a foldingsection 45 including an arm rest plate 45 having a rolled edge 4i'slidably mounted on the lower slide rail. The opposite edge has spacedtubular portions 4-8 that cooperate with similar portions 49 on a plate55 to form a hinge joint, the portions 48 and 4B being connected by arod 5I that extends therethrough. The arm rest plate 45 and the plate 50are of suiiicien't 'combined width to project the lower section of thesash outwardly and retain it in contact with the flanges of the sidewings as shown in Fig. 4. However, torclose the -space at the bottom ofthe lower sash sections, the plate 50 is hingedly connectedalong theforward edge thereof with `a plate 52 having a. hinge 53 attached to theinner face of the .lower rail of each lower sash'section and which ex`tends substantially vertically when the sash are in projected position.When the -sash are .in perpendicular position within the cab, the armrest plate 46 and the two hinge plates 50 `and 52 are in substantiallyparallel relationship as shown in Fig. 2.

When the sash are in retracted position along the sides of the windowopening, the conventional arm rest 54 may be used. This arm rest ishinged to an outwardly extending sill plate 55 as indi- P cated at 56and folds inwardly over the sill plate when in use. When the sash are tobe used, the i arm rest may be swung outwardly into an outoiV wayposition as shown in Figs. 2 and 3.

sash is greater than the width of the opening, each arm rest portion ofthe lower hinge section is provided with a notch 5l and 58 respectively,the notches being of ample depth to allow for movement of the sash.Likewise, the upper outer corner of each upper hinge section is providedwith a notch 59 and 60, respectively, corresponding with the depth ofthe notches 51 and 58. The sash may be connected together to holdrespective sash in abutting contact by means of a latch 6| on one of thesash and which is adapted to engage a keeper 62 on the other sash/Assuming that the sash units are assembled and installed in the windowopening of a cab l, they are operated as follows.

In 'the summer and during pleasant weather, the sash units 4 and 5 aresupported in retracted position at the inner sides of the cab wall asillustrated at the right hand side of Fig. 5. In this position the upperand lower sash sections 23 and 24 are suspended from the upper rail 38and the hinge plates 5B and 52 are folded with the arm rest plates 46vertically and the hinge plates located parallel therewith between thearm plates 4S and the lower sash 2li, the arm rest plate 4S beingsupported on the lower rail 43. The wings 2 and 3 on the outer side ofthe cab may be either folded back against the side of the cab orextended outwardly to protect the eyes of the engineer. The windowopening may be closed by sliding the sash units lLl and 5 toward eachother until the adjacent edges come into abutment as shown in Fig. 6. Inthis position the outer side styles or rails of the units overlap theinner edges of the window opening as also shown in Fig. 6. If theengineer desires :to look up or down the track, the sash units may beslid to retracted position or if the engineer desires complete proectionwhile looking up or down the track, the sash units 4 and 5 are slid to aposition where the outer edge of one of the units will pass the adjacentside edge of the window opening'when the upper sash section is swungoutwardly on the upper rail. This movement may be effected by pushingthe lower section 24 outwardly until it engages the vertical ange I2 ofthe wing at that side of the window. Outward movement of the lower sashsection 24 effects unfolding of the hinge sections composing the plates45, 50, and 52 so that the' plates are supported on the bottom ange E4.of the adjacent wing. The entire unit is then shifted slightly so thatthe notches 58 and 55 engage the edge of the window opening. Thisshifting movement io sufficient to allow the other window unit to belikewise projected between the opposite edge of the opening and theadjacent side rails or. the projected unit. When in projected position,the upper section forms the top, the lower sections form the front, andthe folding'sections form the bottom of an enclosure while the sidewings 2 and 3 form the ends of vthe enclosure.

In projected position the outer side rails seat upon the in-turnednanges of the wings to provide substantially weather tight joints asshown in Fig. 7. After projecting the sash they 'may be readjusted sothat they are in exact center position after which the latch Si isengaged with the keeper 62 to hold the sash units in abutting relation.If it is necessary to return the sash units to storage position, theyare easily manipulated to perpendicular position with thesas'h unitssuspended from the upper rail andv in plane with the window opening soas to provide clearance at the side of the car. The sash are then slidto retracted position alongside the inner wall of the cab after whichthe latches of the side wings may be released and the side wing swungback against the outer side of the cab wall.

From the foregoing, it is obvious that I have provided a sash structurefor the window openings in a cab of a locomotive or the like which is ofsimple construction and easily operated.

It is also obvious that I have provided a simple structure forcooperation with the side wings of a cab to provide a projectedenclosure for complete protection of the engineer when it is necessaryto observe signals in either rearward or forward directions.
